If the object, ends up with a positive charge, then it is missing electrons. if it is missing electrons, then it must have been removed form the object during the rubbing process.
That is false. If an object has a varying speed, then it will have a varying velocity. A velocity has both a speed and direction.
Explanation:
It is given that,
The acceleration of a particle, (negative as the particle is decelerating)
Initial distance, x₁ = 20 m
Initial time, t₁ = 4 s
New distance x₂ = 4 m
Velocity, v = 10 m/s
(A) Calculating initial distance using second equation of motion as :
u = 21 m/s
When velocity of the particle is zero, time taken is t (say). Using first equation of motion as :
t = 2.62 seconds
So, the velocity of the particle is zero at t = 2.62 seconds.
(B) Velocity at t = 11 s
v = 13 m/s
Total distance covered at t = 11 s. The overall path travelled by the particle during its entire journey is called total distance covered.
d = 132.48 m
So, the distance travelled by the particle at t = 11 seconds is 132.48 meters.
Solve for resistance using power and current.
Substitute IR for V in the first formula: P = (IR)I = I2R. Rearrange to solve for resistance: R = P / I2. In a series circuit, the current across one component is the same as the total current. This is not true for a parallel circuit
Answer:
hi, here's the answer
Explanation:
the electric charge of an electron is negative (-ve).
